after further discussion, upstream issued a new fix which reverts previous commits
https://github.com/Cacti/cacti/commit/cfb0733597af97abc92270de4f47cbfa32f9ce8b
which turned out to be insufficient to fix the issue, follow up patches:

https://github.com/Cacti/cacti/commit/4cecb19f6be8b84fa1c7b6450b66176007cb53df
The original issue mentions only a bypass via graph_json.php but there are
additional permission checks missed while checking the issue fixed with the
upstream commits.
